I think I will get it implanted only in one eye, keeping the other one natural. And I will make my cybernetic eye look like a tiger's eye or something stylish like that.

All jokes aside, though, the nerves in the eye are the best place to attach cybernetic implants to a human brain (which is essentially a 12 watt battery). Theoretically, you could have direct control over the heads up display with your mind, without the need for command words.
